I have another Amazon collection issue in that PP will say "collecting 8 orders", "processing 8 orders", then when it goes to the collected page only 7 are displayed. This would be workable if the Amazon orders page didn't have them all coloured red as "collected". I am having to go through the list manually to see which one needs recollecting. The numbers vary. It has been as little as one and as many as five.

I am running the latest version of PP and can provide screenshots to explain anything that is unclear.

One other issue, PP is not correcting postcode formats from Amazon sales like it used to. AB121AB should correct to AB12 1AB but it isn't.
